Patula strigosa, Gour, var. Buttoni, Hemruitı. 
Plate I. Figs. 2 and 10. 
I figure the typical and the toothed forms. See 3d Suppl., p. 220. 
Patula strigosa, Gourp, var. albofasciata, HemPHILL. 
Plate IV. Fig. 9. 
Shell globose, elevated or depressed; whorls six, convex, with a broad white 
band at the periphery, which shows just above the suture on two or three whorls 
of the spire as it passes towards the summit or apex, separating two variable 
chestnut-colored zones; the upper one in some specimens is often very dark, in 
others very light passing into horn-color, and broken into blotches, stains, or 
irregular lines, which pass up a few whorls of the spire and blend with the 
horn-colored summit; the lower zone spreads towards the umbilicus in irregular 
stains, often beautifully clouding the base of the shell, or is often broken into 
irregular revolving lines, and other varied patterns of coloring; striæ rib-like, 
quite coarse in some specimens, in others finer and closely set together; aperture 
circular, ovate, and occasionally pupæform; peristome simple, thickened, sub- 
refiected at its junction with the columella, and partially covering the umbilicus, 
the ends approached and often joined by a callus, the peristome sometimes bearing 
a tooth-like process ;'umbilicus deep, moderately large, narrower in elevated and 
broader in depressed specimens; suture well defined. Greater diameter of the 
largest specimen 17 mm., height, 12 mm.; greater diameter of the smallest 12 
mm., height 7 mm.; with all the intermediate sizes. 
Box Elder Co., Utah. 
Among leaves, brush, and grass, on limestone rock. Altitude, about 4,600 feet 
above the sea. 
This variety of strigosa is so very variable in all its characters I find it quite 
difficult to draw a description that will cover all the individuals which I include in 
it. Ihave given the measurements of the largest and smallest specimens, but there 
are all the intermediates between those figures. 
The above is Mr. Hemphill’s description. An authentic individual is figured 
on the plate. 
Patula strigosa, Gout, var. subcarinata, HEMPHILL. 
Among the shells recently collected by Mr. Hemphill at Old Mission, Cœur 
d’Alene, Idaho, was a marked variety of this species, for which Mr, Hemphill 
suggests the name subcarinata. The specimens vary greatly in elevation of 
the spire, and in the number and disposition of the revolving bands, often 
quite wanting, as in the specimen figured in the Third Supplement. All have 
a very heavy shell, the body whorl of which has an obsolete carina which 
is well marked at the aperture, modifying the peristome very decidedly. See 
the figure.
